This invention relates toa force feed oil can of the type in ,which anoil forcing plunger Vin thebase part of a noiZleQstructure is operatedby manipulation of a lever on the can for the ejection of oil. `In' oilcan` Structure, as for example such as disclosed in my Patent No.1,542,896ydated June 23,1925, complete pumping structure is utilizedincluding an oil Afeed pipe'` extending from the cylinder in the spoutstructure to the bottom of the can and with an inlet check valve thereinand with the cylinder provided with an outlet valve, and, with suchcomplete pump structure,

upon operation thereof by the manipulation of a pump lever on the can,oil may be pumped through the spout during any position ofthecan.

An important object vof yr'nyY present' invention is to simplify theconstruction and'reduce the cost of manufacture ofthe `can ,byeliminating parts, such as the inlet pipe and valve, and pro' viding acylinder in the 'spout Structure which `can be readily lled 'by Atiltingof the 'can and vfrein which, by `Inanipulati0h of a lever on the can,oil may be ejected through 'the spout in any lIO'QStin 0f the een.

A further 'object ofthe invention is to provide a cylinder Space in the"base ofthe spout structure with a plunger "therefor controlled byanactuating rod 'axiallyshiftable by the manipulation `of a lever 4on 'thecan and with the arrangement such that, upon manual depression "of thelever, .theffmovenient vof 'the rod may be rapidly accelerated for quickmovement of the "plunger for spurt ejection of oil' from the cylinderand out of the spout.

A.y further important 'object sto provide improved packing arrangementyfor 'the plunger ,actuating rod with the arrangement such that, after'each return ofthe can operating" lever, vthe lever will engage withpacking structure to Af-Orc@ packiginaterial 'intimately `'agltinst therod to thus`prevent leakage of oil frorn the can 'container totheexterior'A along 'tl'ie'rod A'canv structure embodyingthe variousfeatures' Vof my invention are "disclosed on the 'a'c- 'coinpanyingdrawing in which `Figure 1 is "a 'side elevation ofthe can structure;

n "Figure?2,4 with'the act'liatingzlever lil, normal poe extension butshowing the operating lever depressed for shift of the plunger andejection of oil through the spout structure.

The can shown comprises a c'over Il)r having flange' segments II forinterlocking with flange segments I2 on the can body or container |23Vto hold the edge of the container against a 'gasket I4 Aon the cover soas to form a tight seal when `the cover is applied. The cover is ofsheet metal and has the extension I5 thereon forming the base part ofthe spout structure, the spout Vtip I6 being secured `in the neck part`I'IofY the extension I5. The extension I5 provides the cylinder spaceI8 for the cup shaped plunger |59. The bottom wall of the plunger hasthe inlet pase sag'eway 20, the metal of the bottom around the openingbeing upset t0 provide the `depending flange 2| and the upstandinginclined valve seat flange 22. A check valve 23, shown in lthe form, ofa ball, normally engages the seat 22 tolclose the passageway 20, theball being operable within a cage 24 which at its lower end is heldin`place by the seat uflange 22.

rAt one side of the cover extension I-5, a` guide: bushing 25 is mountedon the cover and secured thereto as by riveting asindicat'edat 2E.Slidably axially in this bushing is the plunger ac- 'tuating rod '21which, at its lower end, extends through the opening 28 in the U-shapedbracket, 29, the rod being intimately engaged by the outer 'leg`30 ofthe bracket to hold the bracketin horizontal position, and notches 31|"inthe rod r'eceiving a split washer 32 on which the bracket seats. Theinner leg 33 ofthe bracket hasears l `34 and 35 extending therefrom andhaving their upper ends rounded toengage the plunger ,along the oppositesides of the depending `flange'Zt of the plunger so that, when the rod2'I is raised, the plunger will be shifted up inthe cylinder space I8, aspring 36 resisting upward movement of the plunger.

Extending across the can top I0 is .the operate.

ing lever 31 whichrhas'the substantially elliptical opening 38therethrough l.for receiving the cover I5. A stiffening andstrengthening llange 3S extends downwardly from the operating lever atits edges, and, `adjacentto the lever opening"38, the flange is extendeddownwardly to provide abutment ears 40 and 4I at diametrally oppositesides of the extension I 5 and Ain engagement therewith, `the loweredges of the ears engaginglthe cover III.

'The'end J42 of the lever 31 dene'cts or inclines downwardly forfengagement by the thunibor finger of vthe can' operator. The otnerenciofthe lever extends over the bushing 25 and has the opening 43therethrough for receiving the upper end of the rod`21 which terminatesin a head 44 above the lever so that when the lever is rotated bypressure on the finger end 42 thereof, the rod 21 and the bracket 29thereon will be raised for upward shift of the plunger in the cylinder.When the operating lever is released, the spring 36 will shift theplunger down against the bracket 29 for return `of the rod to its normalposition with its head againstlthe lever 31; fTo prevent leakage of oilfrom the container to the exterior thereof along the rod 21, packingmaterial 45 is provided and held in place on the outer end of thebushing by a sheet metal cap 46 which frictionally engages the bushing,the outer end of the cap being frusto-conical so that upon downwardpressure thereon the packing material will bef forced radially intointimate engagement with the rod. The packing cap forms a stop for theoperating lever 31 when the lever is swung back to normal position upondownward shift of the rod 21 by the force of the spring 36 so that,after 1 each release of the'operating lever, the lever will tap thepacking cap to shift the cap down against 'the packing to take up anylooseness of the packing and thus keep the packing intimately in en- 5gagement with the rod to prevent oil leakage.

As the lever 31 receives the extension I5 through its opening 38, theaxis X of rotation of i the lever is substantially in the vertical planeof 'lthe minor axisof the opening. The ears 40 and `(4| of the leverhave longitudinally extended fulcrum edges for engagement with the coverto the right of the axis X, the distance of these surfaces from the axisX increasing toward the rear'ends of these surfaces, as clearly shown onFigure 3. With this arrangement, when pressure is exerted -on the end 42of the operating lever, the lever will be rotated on its axis X, theears 46 being swung :forwardly with the lever to bring their fulcrum-tedges 41 progressively into engagement with the .fcover I resulting inraising of the lever at its axis while it is being rotated.l This rotaryand bodily movement of the lever is limited by the engagement of theouter edge of the lever opening 38 with the extension I5, as shown onFigure 5, the rounded heels 48 of the fulcrum edges being then inengagement with the cover.

. The can body may be provided with a handle,

but for manipulation of the can a handle would not be necessary for theoperator may grasp the can body or container in the hand and with one ofhis fingers operate the lever 31. Owing to the inclined end 42 of thelever, pressure thereon will have a vertical downward component, and aradial inward component toward the lever axis. As the lever is beingswung down by the finger, 4the radial pressure -component will increasewhereby the heels 48 of the fulcrum edges will be quickly moved towardthe vertical line of the axis X forV acceleratedk movement of theplunger in rcylinder I8. Furthermore, as the lever is being icreases,and the distance between the finger engaged end of the lever from thispoint correspondingly decreases so that the outer end of the lever isfurther accelerated in its movement for r4shift of the plunger into thecylinder.

When the can is to be used, it is first tilted Vsuiiiciently forunseating of the valve ball 23 for ow of oil from the can body into thecylinder I8.and then, when n; the lever 31 is operated, the shift of theplungerl in :2,340,480 L f @if f the cylinder will exert pressure on theoil for discharge from the cylinder out througlh the spout tip I6, theaccelerated movement of the outer end of the lever in the mannerexplained exerting accelerating pressure against the oil in the cylinderfor rapid or spurt discharge from the spout.

When the cylinder I8 has been lled, the can may be operated in itsnormal or vertical position by manipulation of the lever 31 for forcedejection of oil from the spout, the force of gravity from the can bodythrough the cylinder and spout, or, by operating the lever while the canis inverted or tilted, spurt pressure may be applied, the resistance ofiiow through the more or less restricted spout tip causing sufficientpressure in the cylinder, when the plunger is operated, to hold thevalve '.ball 23 seated against the force of gravity. f

I have Vthus produced a force feed oil can of simple and economicallymanufactured and assembled parts which may beV easily operated'forforced feed of oil from the can container in any position of the can andwithout the need of a feed pipe extending to the bottom of thecontainer. All the operating parts are mounted on the cover structinewhich can therefore be readily applied to can containers of variouscapacity,

I have shown a practical ,and efcient embodifment of the features of myinvention, but I do not desire to Ibe limited to the exact construction,arrangement and Aoperation shown and described as Achanged andmodifications maybe made without departing from the scope of theinvention.
